how do the different frontends deal with displaying large queries?

[Gaute Hope]

Hi,

I am wondering how the different frontends deal with displaying large
queries? Do you just display everything at the time? Or do you display a
limited number and then show more on-demand?

In the on-demand case; how do you get to the same position? Keeping a
query object alive for long might make it invalid when the index is
changed.

Showing a limited number and restarting the query from the same position
might miss threads if something in the first batch has been removed.
